[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-6 This utility model provides a technical solution: a carbon fiber plate crushing and recycling device, comprising:
[0027] The processing box 1, crushing mechanism 2, connecting pipe 3 and filtering mechanism 4 are provided. The processing box 1 is equipped with crushing mechanism 2 for crushing carbon fiber board. The bottom of crushing mechanism 2 is connected to filtering mechanism 4 through connecting pipe 3.
[0028] The filter mechanism 4 is used for the filtration stage treatment of carbon fiber plate debris after crushing. The filter mechanism 4 includes a connecting plate 41, a cylinder 42, an arc-shaped filter plate 43 and a feeding assembly 40. The top of the cylinder 42 is connected to the connecting pipe 3. Two arc-shaped filter plates 43 are arranged inside the cylinder 42. The tops of the two arc-shaped filter plates 43 are set on the inner wall of the cylinder 42 through the connecting plate 41. The feeding assembly 40 for discharging the filtered debris is arranged inside the cylinder 42.
[0029] Specifically, the interlocking alloy toothed roller 22 and toothed section 12 are used for co-crushing to ensure that the carbon fiber plate is fully crushed. The combination of arc-shaped filter plate 43 and moving filter plate 402 realizes automatic classification and filtration of debris to avoid clogging. The blowing mechanism 5, together with the stirring paddle 15, forces out residual debris to improve the recovery rate.
[0030] The feeding assembly 40 includes a slot 401, a movable filter plate 402, a push plate 403, and a cylinder 404. The bottom of the two arc-shaped filter plates 43 is provided with a slot 401 on one side. The movable filter plate 402 is slidably installed inside the two slots 401. One side of the movable filter plate 402 passes through one side of the cylinder 42 and is fixedly installed with the push plate 403. Two cylinders 404 are fixedly installed on the surface of the cylinder 42. The extension ends of the two cylinders 404 are fixedly installed on one side of the push plate 403.
[0031] In this embodiment, the carbon fiber board to be processed enters the processing box 1 through the feed hopper 13. Two alloy toothed rollers 22 rotate in opposite directions under the drive of two drivers 23. The meshing teeth perform strong shearing and crushing on the carbon fiber board. The toothed part 12 located on the inner wall of the processing box 1 cooperates with the alloy toothed rollers 22 to further refine the fragments and ensure uniform crushing. The crushed carbon fiber fragments fall to the connecting pipe 3 by gravity and enter the filtration mechanism 4.
[0032] After the debris enters the cylinder 42, it passes through two arc-shaped filter plates 43 and a moving filter plate 402. The drive motor 16 rotates the stirring paddle 15, agitating the crushed material inside the cylinder 42. Larger particles are intercepted above the arc-shaped filter plates 43, while smaller particles fall through the filter holes into the discharge frame 6. Two electric push rods 8 control the tilt angle of the partition plate 7, causing the debris to be discharged from different discharge ports 9, achieving classified collection. By activating the two electric push rods 8, the angle of the partition plate 7 is adjusted. When large particles need to be discharged, the partition plate 7 is pre-adjusted at the angle, and two cylinders 404 are activated. 4 is a synchronous cylinder 404, which pushes the push plate 403 to move the moving filter plate 402. The moving filter plate 402 slides in the two slots 401, causing large particles of debris to fall into the discharge frame 6 and be discharged from the discharge port 9. When some debris accumulates in the cylinder 42 and cannot fall out, the centrifugal fan 51 draws in air through the air inlet pipe 52 and transports it to multiple exhaust pipes 54 through the transport pipe 53. The high-pressure airflow blows into the inside of the cylinder 42 and blows the accumulated debris into the discharge frame to prevent debris from accumulating. This solves the problems of easy clogging, low efficiency and large residue in traditional carbon fiber recycling equipment, and realizes a high-efficiency, automated and low-loss recycling process.
[0033] It also includes a chip blowing mechanism 5 for assisting in the discharge of residual debris inside the cylinder 42. The chip blowing mechanism 5 includes a centrifugal fan 51, an air inlet pipe 52, a transport pipe 53 and an exhaust pipe 54. The top of the cylinder 42 is provided with transport pipes 53 on both sides. The bottom of the transport pipes 53 is connected to several exhaust pipes 54. The lower ends of the exhaust pipes 54 all penetrate the top of the inner wall of the cylinder 42 and extend therefrom. The air inlet end of the transport pipe 53 is provided with a centrifugal fan 51. The side of the centrifugal fan 51 is provided with an air inlet pipe 52 with a filter section.
[0034] It is worth noting that when the centrifugal fan 51 is powered on, it draws in external air through the air inlet pipe 52 (with a filter), filters out dust, and sends it into the transport pipe 53. The airflow is then distributed along the transport pipe 53 at the top of the cylinder 42 to multiple exhaust pipes 54, forming a high-pressure airflow network. The high-pressure airflow is sprayed downwards from the exhaust pipes 54, impacting the material accumulated inside the cylinder 42 and causing it to enter the discharge frame 6. No manual intervention is required; the fan automatically blows the material, reducing downtime for maintenance and making it suitable for continuous production. The filter in the air inlet pipe 52 prevents external dust from mixing in, ensuring the purity of the airflow and avoiding secondary pollution.
[0035] The bottom of the cylinder 42 is connected to a discharge frame 6. A partition plate 7 is rotatably installed inside the discharge frame 6. Two electric push rods 8 are hinged to the bottom of the partition plate 7. One end of each electric push rod 8 is hinged to the inner wall of the discharge frame 6. Discharge ports 9 are opened on both sides of the discharge frame 6.
[0036] Furthermore, the filtered carbon fiber debris enters the discharge frame 6 from the bottom of the cylinder 42. The two electric push rods 8 are synchronous push rods, which push or pull the partition plate 7 to rotate around its rotation mounting point, changing the tilt direction. When the partition plate 7 tilts to the left, the debris flows to the left discharge port 9. When the partition plate 7 tilts to the right, the debris flows to the right discharge port 9. The angle of the partition plate 7 can be adjusted according to the needs, so that debris of different particle sizes or materials can be discharged from different discharge ports 9, realizing automatic sorting. The angle of the partition plate 7 can be precisely controlled by the electric push rods 8 to achieve the diversion and discharge of debris of different specifications, thereby improving the classification accuracy of recycled materials.
[0037] To ensure the smooth movement of the partition plate 7 and avoid jamming or uneven force, the two electric push rods 8 should be synchronously controlled, using push rods of the same model and with the same stroke to ensure consistent thrust. The two electric push rods 8 should be driven by the same synchronous controller to ensure simultaneous start-up and synchronous extension and retraction.
[0038] Both discharge ports 9 are equipped with anti-collision inclined plates 10 at the top and baffles 11 at the bottom of the discharge ports 9;
[0039] Both the inclined plate 10 and the baffle 11 restrict the rotation adjustment of the partition plate 7 and prevent materials from falling out of the gap.
[0040] The crushing mechanism 2 includes a roller body 21, an alloy toothed roller 22, and a driver 23. Two roller bodies 21 are rotatably installed inside the processing box 1. The surfaces of the two roller bodies 21 are provided with alloy toothed rollers 22, and the two alloy toothed rollers 22 mesh with each other. One end of each roller body 21 is provided with a driver 23.
[0041] It is worth noting that the carbon fiber sheet enters the processing box 1 through the feed hopper 13 and falls into the meshing area between the two alloy toothed rollers 22. The two drivers 23 drive the two rollers 21 to rotate in opposite directions (one clockwise and one counterclockwise). The meshing teeth of the alloy toothed rollers 22 form a shearing and squeezing action, which powerfully crushes the carbon fiber sheet. The crushed carbon fiber fragments fall to the bottom connecting pipe 3 by gravity and enter the subsequent filtration mechanism 4. The high-strength meshing teeth of the alloy toothed rollers 22 can effectively shear the carbon fiber sheet and overcome its high hardness and high toughness characteristics.
[0042] Both sides of the inner wall of the processing box 1 are provided with toothed parts 12 that mesh with the alloy toothed roller 22, and the top of the processing box 1 is connected to the feed hopper 13.
[0043] The toothed part 12 on the inner wall of the processing box 1 cooperates with the alloy toothed roller 22 to further refine the broken material and prevent large pieces of material from escaping.
[0044] A rod 14 is rotatably mounted inside the cylinder 42. A stirring paddle 15 is provided on the surface of the rod 14, and a drive motor 16 is provided at one end of the rod 14.
[0045] Specifically, after the drive motor 16 is powered on, it drives the rod body 14 to rotate, causing the stirring paddle 15 fixed on the surface of the rod body 14 to start working. During the rotation, the stirring paddle 15 continuously agitates the carbon fiber debris inside the cylinder 42, improving the filtration effect. The rod body 14 and the stirring paddle 15 are made of wear-resistant alloy material, which is adapted to the high hardness characteristics of carbon fiber and extends the service life.
[0046] Drive model 23: Siemens 1LE1503-1DB43-3AA4, high starting torque, compatible with frequency converter speed regulation, suitable for high-load crushing scenarios; Electric actuator model 8: Thomson Electrak HD, built-in encoder, supports synchronous control protocol; Drive motor model 16: SEW Eurodrive MOVIMOT; Centrifugal fan model 51: Gardner Denver HIBON; Control system (PLC + HMI) model: Siemens S7-1200.
[0047] The carbon fiber sheet to be processed in this device enters the processing box 1 through the feed hopper 13. Two alloy toothed rollers 22 rotate in opposite directions under the drive of two drivers 23. The meshing teeth perform strong shearing and crushing of the carbon fiber sheet. The toothed part 12 located on the inner wall of the processing box 1 cooperates with the alloy toothed rollers 22 to further refine the fragments and ensure uniform crushing. The crushed carbon fiber fragments fall to the connecting pipe 3 by gravity and enter the filtration mechanism 4.
[0048] After the debris enters the cylinder 42, it passes through two arc-shaped filter plates 43 and a moving filter plate 402. The drive motor 16 is started to drive the stirring paddle 15 to rotate, which stirs the crushed material in the cylinder 42. Larger particles are intercepted above the arc-shaped filter plates 43, while smaller particles fall through the filter holes and enter the discharge frame 6. Two electric push rods 8 control the tilt angle of the partition plate 7, so that the debris is discharged from different discharge ports 9, achieving classified collection.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
